Question

我在使用这段代码时遇到了一些问题，确切地指出了问题的来源，我不确定javascript是否存在问题，但是当我从select.php中选择一条记录时，它最终会停滞不前。（没有任何反应; /）

confirmDelete.js

function fnConfirm(delUrl) {
if (confirm("Are you sure you want to delete this record?")) {
window.location = delUrl;
}

var linkDel = document.getElementById("linkDelete");

linkDel.onclick= fnConfirm;

select.php
